: ## Analysis of the Source Material
1. Core Topic & Intended Audience:
The core topic of the article is the finding of early signs of planet formation within a massive protoplanetary disk named “Gomez’s Hamburger” (GoHam) around an aging star. The discovery is important because it provides a rare opportunity to study how giant planets form at very large distances from their host star.
The intended audience appears to be individuals interested in astronomy, space exploration, and scientific discoveries. The language is accessible but includes some technical terms (e.g., protoplanetary disk, ALMA, photoevaporative winds) suggesting a readership with some existing scientific knowledge or a willingness to learn.
2. Optimal Keywords:
